Abstract
Two-armed lanthanide-binding tags induce significant, long-range paramagnetic effects in the NMR spectra of attached proteins. An enantiomeric pair of rigid, two-armed, cyclen-based tags are reported that...

Pulse EPR-enabled interpretation of scarce pseudocontact shifts induced by lanthanide binding tags
Abstract
Pseudocontact shifts (PCS) induced by tags loaded with paramagnetic lanthanide ions provide powerful long-range structure information, provided the location of the metal ion relative to the target protein is known. Usually, the metal position is determined by fitting the magnetic susceptibility anisotropy (Ī?Ļ?) tensor to the 3D structure of the protein in an 8-parameter fit, which requires a large set of PCSs to be reliable. In an alternative...

Abstract
The use of paramagnetic NMR data for the refinement of structures of proteins and protein complexes is widespread. However, the power of paramagnetism for protein assignment has not yet been fully exploited. PARAssign is software that uses...

Proteinā??protein HADDocking using exclusively pseudocontact shifts
<div class="Abstract" lang="en">Abstract <div class="normal">In order to enhance the structure determination process of macromolecular assemblies by NMR, we have implemented long-range pseudocontact shift (PCS) restraints into the data-driven protein docking package HADDOCK. We demonstrate the efficiency of the method on a synthetic, yet realistic case based on the lanthanide-labeled N-terminal Īµ domain of the E. coli DNA polymerase III (Īµ186) in complex with the HOT domain. Docking from the bound form of the two...
